Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573422, here are decompositions:

29 + 31573393 = 31573422
31 + 31573391 = 31573422
59 + 31573363 = 31573422
61 + 31573361 = 31573422
163 + 31573259 = 31573422
211 + 31573211 = 31573422
233 + 31573189 = 31573422
269 + 31573153 = 31573422

Showing the first eight; more decompositions exist.
